Dr. Brown's Natural Flow Anti-Colic Options+ Narrow Sippy Bottle Starter Kit

The handles are easy for my little one to grip, and I love that the same bottle body works with both the nipple and the sippy spout—makes the switch way less stressful. Cleanup is simple too, which is a huge win for us during this messy phase.

We’ve been using the sippy spout attachment for a week and my daughter figured it out in two days, which never happened with the cups we tried before. The transition kit really does grow with her, and the anti-colic vent seems to keep her from gulping air during feeds.

The three-in-one design is genius—we started with the bottle nipple and just switched to the sippy spout yesterday, no tears at all. The handles are easy for my 9-month-old to grip, and the leak-proof lid has survived more than a few drops onto the floor.
